Amid a wide gap between potentially taxable cryptocurrency activity and the amounts actually reported in France, Chainalysis said, based on cases in other countries, that the tax noncompliance rate could exceed 90%.
According to Chainalysis, potentially taxable cryptocurrency activity in France was estimated at $9.4 billion in 2025. Of this, capital gains accounted for $2.5 billion, income from activities such as mining and staking for $1.7 billion, and cryptocurrency payments for $5.2 billion.
Data from the French tax authorities showed that 24,000 taxpayers reported net cryptocurrency gains for income earned in 2024, totaling €368 million. The previous year, approximately 7,700 people reported a total of €150.8 million.
François Volpoët, head of Chainalysis France, said that experiences in other countries suggest the cryptocurrency-related tax noncompliance rate could exceed 90%. Chainalysis also estimated global potentially taxable on-chain activity at more than $457 billion in 2025, and analyzed that activity subject to CARF accounted for approximately 14% of the total.
